Plans to bypass the committee are abandoned (2,2,3,5)
I believe the answer is:
go by the board
'abandoned' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'plans to bypass the committee' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'committee' could be 'board' (board is a kind of committee) and 'board' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'are' is the link.
Can you help me to learn more?
(Other definitions for go by the board that I've seen before include "Gets abandoned, rejected or ignored" , "get lost" , "Be discarded, rejected, ignored, forgotten" , "accept chalked notice is correct?" , "Take directors' lead" .)
